NotebookLM makes slide decks editable

This is the kind of product update that matters more than a flashy demo because it fixes the biggest usability gap in AI-generated presentations. Once users can tweak a weak slide without rebuilding the whole deck, NotebookLM shifts from novelty toward real workflow utility.

• –Prompt-level slide edits give users finer control over generated presentations without leaving the NotebookLM workflow
• –The update plays to NotebookLM's core strength: grounded outputs built from your own documents, notes, and sources
• –For research-heavy users, editable decks make the tool more useful for internal briefings, study summaries, and draft presentations
• –It also shows Google is polishing the messy post-generation editing step, which is where many AI productivity tools still fall apart
